The letter wall: a gallery of real mail, with consent built in
Scroll the letter wall and you will see what this hobby actually looks like: wax seals, watercolour envelopes, three-page letters tied with string, pressed flowers that survived two borders. Every photo is a real letter between two real pen pals. And every single one is there because both of them said yes.
How a photo gets on the wall
- Someone shares it. On a friendship page, either pen pal can upload a photo of a letter from their exchange, old or new, with a caption and a note of whether it is a letter they sent or received.
- The other approves it. The photo goes to the other pen pal first, marked "awaiting approval." Nothing is public yet. They see exactly what would be shown and choose to approve or decline.
- Then the world sees it. Only after approval does the photo appear on the public wall, credited to both of you by first name and country, with the letter's direction: "From Naveen to Riya, India → India."
Decline, and the photo is deleted. Not hidden, deleted.
You can always take it back
Consent on the wall is continuous, not one-time. Either pen pal can take down an approved post at any moment, no reason needed, and the photo is permanently removed from storage. The person who posted it and the person who approved it hold equal power over it forever.
What to keep out of frame
The wall is public, so photograph the artistry, not the logistics. Before you upload, check the photo for:
- addresses on envelopes (yours or theirs)
- full legal names
- phone numbers, email addresses, or anything else that identifies where someone lives
A good habit: photograph the letter open on a table, not the envelope front. If you want envelope art on the wall, cover the address block with a sticker or crop it out.
Why we built it this way
Letter photos are deeply personal, and a letter always belongs to two people: the one who made it and the one who holds it. A platform that let either person publish unilaterally would eventually publish something the other regrets. Requiring both signatures makes the wall slower to fill and much better to trust, which is the same trade every part of Letter Trails makes, from address sharing to disappearing chat.
Tips for a great wall post
- Natural light, plain background, letter slightly angled. Paper photographs beautifully.
- The caption is your postcard to the world: one line about what made this exchange special.
- Received something wonderful? The moment you mark a letter received is the perfect time to share it, and Letter Trails will gently suggest exactly that.
